Enum webrender_api::TextureTarget

pub enum TextureTarget {
    Default,
    Array,
    Rect,
    External,
}

Specifies the type of texture target in driver terms.

Variants

Default

Standard texture. This maps to GL_TEXTURE_2D in OpenGL.

Array

Array texture. This maps to GL_TEXTURE_2D_ARRAY in OpenGL. See https://www.khronos.org/opengl/wiki/Array_Texture for background on Array textures.

Rect

Rectange texture. This maps to GL_TEXTURE_RECTANGLE in OpenGL. This is similar to a standard texture, with a few subtle differences (no mipmaps, non-power-of-two dimensions, different coordinate space) that make it useful for representing the kinds of textures we use in WebRender. See https://www.khronos.org/opengl/wiki/Rectangle_Texture for background on Rectangle textures.

External

External texture. This maps to GL_TEXTURE_EXTERNAL_OES in OpenGL, which is an extension. This is used for image formats that OpenGL doesn't understand, particularly YUV. See https://www.khronos.org/registry/OpenGL/extensions/OES/OES_EGL_image_external.txt
